Hello, last 2 years i decide to invest to some altcoin in market.. for 1 altcoin is worth than $1.. now, 1 altcoin is worth than $0.0036..
Is the company still exist or already closed?
What coin did you invested for 2 years ago? it only shows that altcoin is more of a pump and dump and by saying if that company still exist. Do you mean the developers?
Forget if it's a company or an ICO project, it only means that many took profits from that coin for the last years and there's no progress on it and it's starting to be dead while it's still surviving with a value of $0.0036.
Why on market this coin still exist?
Because there are people who are still trading on that coin and you can check on how much the market cap of that coin which means that there's still money on it.
